Answer: 1.4.1 To calculate the value of the machine before VAT was included, we can use the formula: Value before VAT = Value after VAT / (1 + VAT rate)
Given the total cost of the machine after VAT (including the deposit) is R183x35, and assuming the VAT rate is 10%, we can calculate the value before VAT as follows:
Value before VAT = R183x35 / (1 + 0.10)
1.4.2 To find the total cost of the machine if it is bought on terms, we add the deposit to the total cost after VAT. Using the given deposit of 10%, we can calculate the total cost as follows:
Total cost = R183x35 + (10% of R183x35)
1.4.3 To determine the depreciation and verify Paul's estimation, we can use the formula for depreciation: Final value = Initial value * (1 - depreciation rate)^n, where n is the number of years.
Given the initial value of the machine is R4,500, the depreciation rate is 15% per year, and the time period is 2 years, we can calculate the final value and compare it with Paul's estimation.
